help with bash script

[R Kimber]

I'm trying to do something very simple but failing, and would appreciate
some pointers.

I'm trying to create a script that executes a command on a series of files
one-at-a-time, pausing between each execution.  The input files are all in a
single file, one on each line. I have
.......................
#!/bin/bash
cd <to working directory>
cat <file with list of input files> | while read FILECHECKED do

   <command> "$FILECHECKED"
   echo
   RESPONSE="Z"
   echo -n Press a key to continue....
   while [ "$RESPONSE" = "Z" ]
   do
      read RESPONSE
   done
   echo
done
......................

The command executes, but there is no pause between the processing of each
input file.  I've tried various variations using the read command, to no
avail.  Curiously, if I add
echo "$FILECHECKED" and "$RESPONSE"
just before the final 'done', it prints out the name of the file it has
just processed and the file it is about to process - not 'Z'.

I'm obviously doing something stupid.
